Uh-oh. Good catch. I didn't notice that.
Copied from the text:
In drawing distinctions between individual human beings, certain tasks are easier than others. In the context of "affirmative action" and other preferential programs, the easiest differentiating principle to discuss or administer is sex. In this area, human beings come only in two biological flavors, each fairly easily distinguished by a characteristic chromosomal pattern of XX (female) or XY (male). Chromosome sets such as XXY can occur, but they are quite rare. For the most part, the male/female dichotomy is one of conceptual clarity.
I just noticed the paper was published in 1994. Wow. By today's standards, the writer would be a "right-wing bigot." LOL.
I like the cut of your jib!
Yes, it's amazing what revolution in mores and cultural norms has taken place in the span of a scant twenty years!
